Electrode manufacturing - behind the scenes

Radiometer offers a range of more than 300 electrodes - combined pH, glass or reference electrodes, metal electrodes, ion-selective electrodes and conductivity cells - for every application and budget

Many electrodes in the Radiometer Analytical range feature Red Rod technology - a unique concept developed by the company swhich ensures fast response time across a wide temperature range.

Electrodes are manufactured in Villeurbanne, France, using a combination of traditional know-how and state-of-the-art technology.

It takes between two and 11 days to manufacture a combined pH electrode, depending on the type.

The most spectacular stage of the process is the blowing of the glass bulb from a blob of molten glass heated to 1200C.

To explain this little-known yet fascinating process, Radiometer Analytical has produced a fully illustrated technical article which can be downloaded from its website.
